WOW! ....I look so young!!!
This is an introduction to IPv4 addressing and Subnetting. But the same method can be used for IPv6.
(Please excuse the quality of this video...it is very old and it was one of my very first videos when I started on UKposts...this video started out to be a JOKE...and it eventually became a hit...who knew?)
For those of you that are looking for a more complete understanding of IPv4, HEX Conversions, Vlans, Routers & other courses related to Cisco and/or the CCNA certification, I'm happy to announce that I now have full courses available at the www.GlobED.net website.
Also, for those wondering why I start by 2...I have a YT video called "Counting by 2 and double as you go" that will clarify the method to my madness ;)

I have watched my college professors video on this, another random guy, and this one. (all 3 were around 45min) and this is BY FAR the best video on the subject. Thank you very much.

@thenetworkingdoctors 10 років тому
@jasmit kaur sahi ...when you count for subnets or hosts, you start by counting from 2 and double as you go (i.e.: 2,4,8,16,32,64....etc.). Also, when you count for subnets you count from Left to Right. When you count for hosts, you count from Right to Left. So, you always subtract 2 from the HOST side and you only subtract 2 from the NETWORK side if you are NOT using the Zero subnet. In my examples, the only time, I count by 1 and double as I go (i.e.: 1,2,4,8,16,32,64128) is when I count the BIT values in each OCTET. I do have a YT video called "Starting at 2 & Double As You Go"...this might clarify the method to my madness.

+The Networking Doctors I've been out of the IT game for a few years, and even when I did work with submasks, I didn't have to do much unless it was giving a machine a static IP. Aside from that, all the networks were already built before I started working at my job, so all these lessons never really came up. Im looking to get back into the IT industry, and wanted to brush up on my facts. I had no idea that creating subnets like this had so many facets. I admit, I had to watch this video at least 5 times in a row, pausing, taking notes, copying his diagrams....I figured out on my own about counting by doubling each number in the sequence beginning by 2 for subnets (left to right) and same but except right to left for the hosts; but I admit it took several times of me wondering why the hell he didn't start with 1. It all makes sense now, reading these comments its funny how many people it threw off about why he began by 1 and then by 2; I finally understand sub networking now, and this video is the best i have seen on youtube. Just a suggestion +The Networking Doctors but since this is the most popular youtube video on the subject and getting close to 1 Million views, I think it would be helpful to make annotations (like scrolling text perhaps, pop up windows?) explaining why a you switch from starting at 1's and then switching to 2's. The Bit Sequence vs. The subnet/host (2's) sequence. If you just added that little note in the video itself each time you do that then it would really be a perfect video. Just a thought, but love your teaching style. You sound hard and strict in a way, like a military person really taking us all on a sub netting bootcamp. Your demeanor really gives us incentive to get this down and push us to think hard and logically. This has helped tremendously, please continue putting video's like this on youtube!
@thenetworkingdoctors 8 років тому
Thanks everyone! ...and Jared Sanchez, I'm glad you got it! I do have another YT video called "Counting by 2 and Double as you go" that explains why it's done in this manner. Also, in the next few weeks, I'll be making a similar video since this one is over 3 years. However, it is the most popular video that I have. This video started out as a sort of joke for UKposts and it turned out to be the one that launched my online career as a Cisco Instructor...who would of thought? 😉

@@thenetworkingdoctors I was wondering. Are any of your labs downloadable. I'm having a hard time recreating the network based on the topology you show in your videos. Right now I'm working on your eigrp lesson. The 1841 routers you use don't have a serial port so I'm using generic. And I tried a cidr 30 (255.255.255.252) on my ip addresses but they are conflicting with each other. So I adjusted them a bit changing the third octete seemed to work. But now they aren't working on the 10.0.0.0 network. I'm assuming I would just need to do a few more configurations with eigrp. I'm sure I can figure it out so it will work. But I'm having a bit of difficulty.

@Whodamanimal 4 роки тому
This confounded me as well. I believe the case is: Count for hosts, right to left, starting with 2. Count for subnets, left to right, starting with 2. The increment (and therefore the broadcast calculation number) is derived from the BIT VALUE, which starts with 1 (starting from the right). This is why he counts the hosts and subnets on the bottom and counts the increment number and the broadcast calculation number on the top. Bottom: Start with 2's. Top: use bit value. Please correct me if I'm wrong about this. I've started taking Laz's CCNA class on Udemy. It's great! Thanks Laz!

Why do you start from 1 sometimes and you start from 2 sometimes.
@thenetworkingdoctors 9 років тому
You are not alone in this...and your in luck, because I do have a YT video that explains this. It's called "Counting by 2 and double as you go". Hope it helps! 😉

+Ademola Ajibade I think long story told short: You start from 1 (or rather 128) when you count to find the increment while you start by 2 when you count for hosts and subnets.
@JoshuaHults 8 років тому
+Ademola Ajibade for now just memorize 1, 2 ,4 , 8, 16, 32, 64, 128 ........ lol

+The Networking Doctors 76543210.....binary is 2 ... so every number is power with 2 sooo 2^7=128 2^6=64 2^5=32 2^4=16 2^3=8 2^2=4 2^1=2 2^0=1 i follow i like this is it correctly .......

Thank you for this video. It helped me pass my Network+. 823 out of 900. This is the best IPv4 subnetting instruction I've run across. Thanks again.
@maskonoroff 7 років тому
I've taken so many network classes and two CCNA courses. Never gotten an explanation like this. WOW dude your extremely awesome. I have ADHD and this really explained subnetting and its so easy hahaha. Thank you Thank you. It feels so good when it finally clicks after two semesters of network classes.

My husband has been teaching me this subject and at first I get it and then forget it. He gets frustrated and the. so do I and then want to give up. It’s just a matter of practice and reviewing for me. This is a great video for reviewing, thank you :)

Hey Laz, I have watched this again as many times before!, I truly love this tutorial because it's the best subnetting video on the net in my opinion. I want to say that this video helped me sooo much as I had a penny drop moment after watching this vid... I'm somewhat a subnetting master now because of you! I watch this video on different occasions because it brings back memories of how useful it was to me when I struggled with IP addressing. Laz you have my vote and respect always you are truly the king of IP.
